Removing rough edge from dremel cut?

post #1 of 8
Thread Starter 
Hi, I've cut some parts of my casing to fit a larger motherboard, how do I remove the rough edges created by the dremel?

I bought a series 200 dremel that includes some white polishing heads and a polishing compound/putty. Should I use that/

I also have some sandpaper but I think it's too fine (800 grit)



Thanks in advance.

This worked great for me when I was modding my 650D. Picked one up at home depot for about 3 bucks. I've tried those polishing tools my dremel came with but wasn't a huge fan. Finished with some fine sandpaper.

Does the file tool come in different grit?

What grit of sandpaper do you recommend to buy to finish the job?

Straight from that wiki:

Files come in a wide variety of materials, sizes, shapes, cuts, and tooth configurations. The cross-section of a file can be flat, round, half-round, triangular, square, knife edge or of a more specialized shape.

You'll want a hand (mill) file with medium then to fine teeth. Could also use an assortment of emery cloths if you need but not sure what finish type you're going for or what's available to you.

Angle grinder + sanding flip flop disc for the smoothest possible handheld edge removal. You can start from 20 grit all the way to around 160-320 ish if I'm correct. There could be specialty abrasive shop around that have rougher/finer discs though.

Or the burring bit on your Dremel. It's called rotary file for no reason

Or use a grinding disc/flap disc and be vewy vewy careful!
